I don't believe being a heterosexual is genetic. Obviously it's due to some environmental factors. A guy spending too much time around women can cause them to feel similar to the women and lead him to behave like a lesbian.

I don't want to go as far as to say that heterosexuality is sick (that might cause some backlash) but how can someone contemplate raising a child within such a contentious houshold??? I mean if god had wanted men and women to be together he would have made them more similar.

And it's dangerous in such a large society for someone to have a dysfunction like heterosexuality, that kind of behavior leads to unwanted pregnancies in a world that is already full of children without parents and shortage of resources.

Some recent studies have shown that straight men have significantly lower levels of testosterone than gay men. This might be caused by the fact that they have so much less sex due to their attraction to people on a completely different sexual drive, but it could also be an indicator of a biological component.

Personally I don't have a problem with straight people, I mean I have straight friends, but how could someone think that is natural?

Men are supposed to be with men, obviously, and women with women, I mean even when they are deviant heterosexuals they still spend a majority of time with members of the same sex... that should tell you something!
